Hornets
DangerousWhat it is
Social wasps that build paper nests in trees, shrubs, structures, or cavities depending on species. They can defend nests aggressively and may sting repeatedly.
How to recognize it
Large wasps, such as bald-faced hornets with white face markings, and football-shaped paper nests.
Where you will find it
Trees, shrubs, and structures, depending on the species.
Why it matters
They defend the nest aggressively and can sting repeatedly.
What to do
- Keep your distance from nests and do not swat, knock down, or spray one. Disturbed nests trigger defensive stinging.
- Keep outdoor food, drinks, and trash covered, especially in late summer.
- Keep children and pets away from the area and note where the nest is.
- Contact a licensed pest professional for nest removal.
When to call a professional
- You see a nest on or near the house, a door, or a play area.
- Anyone is allergic to stings.
- Insects enter the home from a wall, soffit, or attic.
